Hundreds of north Los Angeles County residents are expected to crowd a Board of Supervisors hearing today in a last-ditch effort to derail plans for a large sand and gravel mine in Soledad Canyon.
The mine would be operated by Transit Mixed Concrete Co., a subsidiary of the Mexican concrete giant Cemex, on 460 acres just east of Santa Clarita. It has sparked one of the fiercest quality-of-life battles in the growing suburbs north of the San Fernando Valley.
The city of Santa Clarita lined up several charter buses to deliver homeowners, environmentalists and elected officials to the hearing, after which the board is scheduled to vote on the plans. If the project is approved, the mine could open within two years.
Opponents from Santa Clarita, Agua Dulce and Acton say the mine would lower property values, exhaust water supplies and clog freeways with trucks.
Agua Dulce resident Tana Lampton said she is also worried that lights at the mine would ruin her view of the stars.
"This will mean no more dark skies," she said.
Though Santa Clarita officials are exploring legal options to stop the mine, the supervisors' decision on Cemex's mining permit application would be the last major hurdle for the project, said Brian Mastin, an environmental affairs manager for the company. The mine already has federal approval.
Cemex officials argue that concrete helped build communities like those in the Santa Clarita Valley. The mine would extract 56 million tons of sand and gravel over 20 years, 10% of what Los Angeles County's building market consumes, Mastin said.
Arguing the mine will barely be noticed by residents, Mastin said it will comply with anti-dust regulations, stop using water during drought conditions and have minimal effects on traffic. He said a federal study concluded that new trucks would increase Antelope Valley Freeway traffic by just 1.5%.
"It's a very low-impact situation," he said.
In April, another bused-in crowd of Santa Clarita protesters cheered supervisors when they voted to reject an earlier version of the proposal. Since then, some key obstacles to the mine have fallen away.
As a result, even Santa Clarita officials sound pessimistic. In a recent e-mail to residents, City Manager George Caravalho said he believed the supervisors were ready to sign off on the project.
"The protests of thousands of residents has fallen on deaf ears," he said.
